7b all whom 'itf may concern: Beit known' that I, LnoN P. Lowa, a citizen of the United States, residin at San Francisco, in the county of San Francisco and State of California, have inyented certain-new and kuseful Improvements in Methods of Colo mgl, o f winch the following is a specification.

his invention relates to an improved -methodo coking, and is especially valuable for utilizing `for this purpose the terry residues from gas-making. Heretofore' these residues have been used for feeding furnaces. The object of m invention is to provide a more economica method of utilizing the same. in my improved method I separate said terri residues into. hydrocarbon gases and. coke, and I therefore not only utilize the heat of combustion ofthe hydrocarbon gases -for any desired urpose, as for heating refractory materia forges-making or otherwise,.or use said hydrocarbon gases directly Vas'commerciai gas, hut in addition I obtain a at the burner 14 above coke.

5o dues having been fed into valuable commercial `product'--namely, coke. One of many forms of apparatus which may be used for oarrying'out my improved method is shown in the accompanying drawing.

1n said drawing the figure .is a. vertical section of a gas-generating apparatus,

Referrin Vto the drawing, l're'presents a casing Vline with refractory material 2. Upon arches 3 are supported loose piles' o refrac- 1501")r inaterial. The lowerportion' of said casing below said arches forms a combined coking and combustion ch mher 5,nto which bituminous coal or the tais-y and other carhonaceous resid ues from gas-making may be fed through the door 7 is a steam-supply ipe, 13 an oil-supply pipe, and an air-supp y pipe foi-burning oil 'said coal o1' terry resi- (g-ehamlzver.A

12 is a pipe for conduct-ing o'i' the gas generated in the Casin 15 is a Coal or terry resi the co'king-charnber, oil is admitted tothe oil-burner 14 and' air is supplied for combustion of said oil. A The Haines and hot gases arising from the *combustion of the o'il pass through the-arches The process is as follows:

door whic is opened to remove the 3 and highly heat thesame.

The resid'iics in the racking-chamber are thus colrcd by the radiant heat from the arches 3' of said chamber and also by the combustion of the oil and of the ases arising during the Vheating of said resi( ues, asin the beehive process of making supplied for the combustion of said gas. The products of combustion of the oil and gases, after highly heating said arches 3, pass through. the piles oA refractory material 4, highly heating the same by the flue 9 and stack 11. The air is now oil are assed by the npcs 7 and 13 throu h the hig y -heated re ractory material, ma ing gas .t erefrom in the usual manner. the same time the gas which continues to b'e distilled vfrom the coal or tarry residues is added to the gas thus formed and with said gas is conducted bv the pipe 12 to'the washers and scrubbers in the usual manner. By this method the tarry residuos are utilized more economicall)v than heretofore,v as' their heat values assist in gas-making and coke is obtained as a product of the process.

the use` of tarry residues in operating 'this process, but covers also, broadly, the roking of coal thereby.

I claim- Thevmethod of simultaneously coking and making gas which consists in charging hydrocarbonaccous material into a Uniting-chainber, then admitting oil and airintosaid chamber and burning the oil above'said hydrocan bonaceous material and atthe same time partly coke the hydrocarbonucmnis-n lntorial, and then discontinuing the zulmiss'io'n of :fir but continuing the admission or'o'ihii'itotsdid Ichamber and passing the vapors of said I )'lso distilled from the hydroczrb:)nacco'us Imate-v rial through the refractory material to 'ineke gas, substantially. as described.

In witness whereof l have hereunto/set my .hand in the presence of two subscribing witnesses;
